I've really got a soft spot for the old Relums, and FEG who I believe were the manufacturers were quite ahead of there time , have a look at the Relum Repetier rifle and the Relum Hurricane pistol from the 1960's to see where El Gamo got some of their ideas from, that is unless El Gamo come up with the idea first and FEG copied them ? ..
